A Geometric View on Bilingual Lexicon Extraction from Comparable Corpora
نویسندگان
چکیده
We present a geometric view on bilingual lexicon extraction from comparable corpora, which allows to re-interpret the methods proposed so far and identify unresolved problems. This motivates three new methods that aim at solving these problems. Empirical evaluation shows the strengths and weaknesses of these methods, as well as a significant gain in the accuracy of extracted lexicons.

Revisiting comparable corpora in connected space
Bilingual lexicon extraction from comparable corpora is generally addressed through two monolingual distributional spaces of context vectors connected through a (partial) bilingual lexicon. We sketch here an abstract view of the task where these two spaces are embedded into one common bilingual space, and the two comparable corpora are merged into one bilingual corpus. We show how this paradigm...
متن کاملTowards a Generic Approach for Bilingual Lexicon Extraction from Comparable Corpora
This paper presents an approach that extends the standard approach used for bilingual lexicon extraction from comparable corpora. We focus on the problem associated to polysemous words found in the seed bilingual lexicon when translating source context vectors. To improve the adequacy of context vectors, the use of a WordNetbased Word Sense Disambiguation process is tested. Experimental results...
متن کاملLooking at Unbalanced Specialized Comparable Corpora for Bilingual Lexicon Extraction
The main work in bilingual lexicon extraction from comparable corpora is based on the implicit hypothesis that corpora are balanced. However, the historical contextbased projection method dedicated to this task is relatively insensitive to the sizes of each part of the comparable corpus. Within this context, we have carried out a study on the influence of unbalanced specialized comparable corpo...
متن کاملA Combination of Models for Bilingual Lexicon Extraction from Comparable Corpora
In this paper we present a method to extract bilingual terminologies from comparable non-aligned corpora, by using multiple linguistic knowledge sources, such as: non-parallel corpora, bilingual thesauri, a preliminary bilingual dictionary, etc... We focus on two core technologies: bilingual lexicon extraction from comparable corpora and expansion through thesauri categories based on different ...
متن کاملImproving Corpus Comparability for Bilingual Lexicon Extraction from Comparable Corpora
Previous work on bilingual lexicon extraction from comparable corpora aimed at finding a good representation for the usage patterns of source and target words and at comparing these patterns efficiently. In this paper, we try to work it out in another way: improving the quality of the comparable corpus from which the bilingual lexicon has to be extracted. To do so, we propose a measure of compa...
